As mentioned, when you get into that higher magnification it is easy to loose game because of the narrower field of view. The bull in my avatar was taken near 700 yards. When I had the the NF turned up to 22X I lost him in the field of view. I eventually had to adjust it down to around 15 power so I could get on him and take the shot. Just my experience and why I think 3-18 is optimum for hunting.If I had access to look through a few VX6HD it would sure help. I will admit I have been tempted to go with the 3-18. But I better stick to my gut and go 4-24.
